That's the same model Saban used to rebuild Bama so quickly. Oversigning and then run off the kids that don't pan out. Butch's entire philosophy for this program is competing at all positions, no one can get comfortable or complacent. However, the rebuilding is almost complete and you will see less oversigning with each coming class as the numbers equal out.
Exactly. Such an easy concept to grasp if you aren't stubborn and don't have hours of life and thousands of posts dedicated to a futile stance that the coaches don't know what they're doing and are going to run the program into the ground by having a handful of players leave (when it's necessary to stay under scholarship limits, no less).
